How do you know Vader didnt send troops to investigate? He obviously sensed Luke was still alive. Maybe the TIEs that intercept the Falcon were there to search for Luke and stumbled upon it rescuing him. That's the way I see it.
Oh I totally agree, I was just making a point about things not being explained in all 6 of the SW films. But as I said I don't care that things aren't explained on screen. Exposition is can be a curse on cinema if over used.
